Researchers Create Glossary Of Gestures Used By Wild Chimpanzees

For the first time, scientists from the University of St. Andrews in Scotland have decoded the meaning behind the various gestures that chimpanzees use to communicate with one another, observing more than 80 wild Ugandan primates in order to compile a glossary of their hand and body movements.

Writing in the July 2 edition of the journal Current Biology, St. Andrews primatologists Dr. Catherine Hobaiter and Professor Richard Byrne explained that they monitored wild chimpanzees in the rainforests of the African nation and discovered that the creatures use a total of 66 gestures to intentionally communicate 19 different and unique meanings.

According to Tom Brooks-Pollock of The Telegraph, among the gestures detected by Hobaiter and Byrne included tapping another chimp in order to ask them to stop doing something, flirting by nibbling on a leaf, making a flinging motion with the hand to ask another chimp to move away, and raising an arm in order to ask for an object.

The study authors said their findings confirm the long-held notion that the creatures most closely related to humans biologically truly do have a purpose when they communicate with each other. While experts had known that they used gestures to communicate, this is the first study to successfully figure out what they are saying.
